Courtesy of John Coulthart's blog - a link to a rare book dealers site which has put up good quality scans of the printed programme produced for Metropolis' London premiere in March 1927. It contains articles by (or at least attributed to) Lang (who writes a short piece entitled 'What I Have To Say' which boils down to how he can't express everything he has to say in words), Thea von Harbou, Rudolf Klein-Rogge, Rudolf Frohlich and Carl Freund and lots of pictures. Fascinating item.
